Feline chlamydiosis (also called feline pneumonitis) is caused by the bacterial organism Chlamydophila felis (C. felis). The C. felis organism does not live for very long in the environment, so infection is generally spread through direct or close contact with a sick cat. Because infected cats sometimes sneeze, contact with these droplets can also spread the infection.

Diabetes mellitus is an illness caused by the body’s inability to either make or use insulin, which is a hormone produced and released by specialized cells in the pancreas. Insulin permits the body’s cells to take sugar (glucose) from the blood and use it for their metabolism and other functions. Diabetes mellitus develops when the pancreas doesn’t make enough insulin or when the body’s cells are unable to use available insulin to take glucose from the blood.

Feline distemper is the common name for the feline panleukopenia virus (FPV), also called feline parvovirus. Despite the name feline distemper, this contagious disease does not affect a cat’s temperament. Rather, FPV causes serious disease in infected cats and can be fatal.

Feline leukemia virus (FeLV) is also contagious among cats. Unlike many other viruses that enter specific cells in the body and destroy them, FeLV enters certain cells in a cat’s body and changes the cells’ genetic characteristics. This permits FeLV to continue reproducing within the cat each time infected cells divide. This allows FeLV to become dormant (inactive) in some cats, making disease transmission and prognosis (outlook) difficult to predict.

Feline distemper is the common name for the feline panleukopenia virus (FPV), which is sometimes called feline parvovirus. Despite the name feline distemper virus, infection with this virus does not affect a cat’s temperament. Rather, FPV causes serious disease in infected cats and can be fatal.

Rabies is a dangerous virus that infects animals and humans worldwide. The virus is generally fatal in all species, and any warmblooded animal can become infected. Foxes, skunks, coyotes, and certain rodents are implicated in many cases of exposure. Surprisingly, cats are more commonly involved in transmission of rabies than dogs. In fact, cats are the number-one domestic animal carrier of rabies in the United States.

Hypertrophic cardiomyopathy (HCM) is a disease of the heart muscle. The exact way the disease occurs in cats is unknown, but the result is that the heart muscle becomes extremely thickened with normal and abnormal cells. The thickened muscle can’t relax and contract normally, so HCM decreases the amount of blood that the heart can handle. Heart failure results because there is so little room for blood to collect and be pumped out to the rest of the body.
